It’s no surprise that Rove and his ilk are attacking Warren. She’s a major threat to the Republican Party and its allied corporate backers for two reasons.

Number one: she’s running even with Brown in a race that may very decide control of the Senate.

Number two: her reformist background and brand of progressive populism is deeply resonant right now. Unlike so many in Washington, she’s taken on the banks and their allies, is not beholden to them, and is not afraid of them. That makes her dangerous to the political establishment in both parties.
